Primary impacts of an outbreak are defined as the direct and immediate consequences of the epidemic on human health. Secondary impacts are defined as those caused by the epidemic indirectly, either through the effect of fear on the population or as a consequence of the measures taken to contain and control it. For clarity and simplicity, we are not including the consequences for the individual or the family of being sick or dying from it, such as time spent in hospital, treatment expenses, loss of the family breadwinner, bereavement, survivor stigmatization, etc. as those would be independent from the response to the epidemic.
